Asphalt Tonnage Calculator
Hot-mix tonnes for a paving area at compacted thickness.
US estimators carry '110 lb per square yard per inch' — same 2,400 kg/m³ in disguise. Order against COMPACTED thickness; the paver lays ~25% thicker before rolling.
Formula
Asphalt Tonnage Calculator is a free asphalt calculator for civil engineers, contractors and quantity surveyors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Asphalt Tonnage Calculator
Hot-mix tonnes for a paving area at compacted thickness. The calculation implements t = A × thickness × 2,400 kg/m³; handy: ~120 kg/m² per 50 mm (MoRTH / Asphalt Institute estimating). US estimators carry '110 lb per square yard per inch' — same 2,400 kg/m³ in disguise. Order against COMPACTED thickness; the paver lays ~25% thicker before rolling.

Frequently asked questions
What formula does the Asphalt Tonnage Calculator use?+
It computes t = A × thickness × 2,400 kg/m³; handy: ~120 kg/m² per 50 mm, per MoRTH / Asphalt Institute estimating. The formula is displayed under the result.
What should I keep in mind when using this calculator?+
US estimators carry '110 lb per square yard per inch' — same 2,400 kg/m³ in disguise. Order against COMPACTED thickness; the paver lays ~25% thicker before rolling.
Does it include wastage?+
Yes — standard wastage/bulking factors are built in and stated in the formula line, so the quantity is an orderable number, not a bare geometric volume.
Is the Asphalt Tonnage Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
